keep getting this 530-189-2472 and no message (hangs up)

Tried calling  back and get 'number you have dialed is incorrect'

If you have blocking capabilities with your phone then do just that , a supposed Allstate agent will arrive at your door minutes later claiming they have to take pictures of your residence.

Got a call from SAME number using my own 256 area code.  I don't answer unknown numbers.  
The commenter above has the right of it.  I am seeing the 189-2472 complaints abound but using ALL diff area codes.  Be wary of answering it.  It may be a spoof number calling to find out if your line is active them sell your number to telemarketers.  
256-189-2472

I have the same complaint about this number, but with a different area code (206).  No such number when trying to call back.
